The petition was filed with the Moscow Basmanny Court; the prosecution asked to change the verdict and prohibit the sisters from taking certain actions until December 28, 2018.

A prohibition of certain actions is similar to home arrest but is a milder measure since they can go out, meet with certain people, use communication devices and the Internet. The accused must also show up before the investigator or the court whenever summoned.

Maria, Angelina and Kristina Khachaturyan were detained on July 27 after they had allegedly murdered their father Mikhail Khachaturyan, 57. They are charged under item (g), part 2 of Art. 105 of the Criminal Code (murder committed by a group of persons by previous concert, or an organised group).

The sisters, the eldest of whom is 19 and the youngest 17 years old, all confessed and said their father had been abusing them. On August 2, the court sentenced the girls to custody until September 28.

In early September, the accused girls were examined at the Serbsky Institute. The experts found the two older sisters sane, while the youngest one, Maria, was allegedly unaware of what she was doing at the time of the murder. If her guilt is proven, she might avoid criminal responsibility.
